Popis: Degussa P25 TiO 2 was evaluated as a catalyst for vapour phase methylation of phenol. It gave an optimum conversion of 32% at 450 °C and formed predominantly the ortho -, para - and meta -cresols. The activity selectivity profiles are discussed in terms of the acid–base properties of the catalyst and the BET surface areas. A new mechanism is proposed to explain the observed product selectivity.
